Hearing loss caused by cochlear hair cell loss is the most common process afflicting the hearing impaired. Recent studies in the avian cochlea following ototoxic drug and noise damage have demonstrated a remarkable capacity for anatomical and functional recovery. Hair cell regeneration has been shown to play a major role in this recovery process. Future studies may one day make hair cell regene...

Background Cochlear implantation is an approved treatment which can be used to treat severe to profound hearing loss. Imaging before cochlear implant surgery is very important in decision making and assessing the temporal bone anatomy for surgery. We aimed to assess the diagnostic value of high resolution CT scan (HRCT), and MRI of temporal bone in candidate pati...

Objectives: Profound hearing loss encounters children with delay in speech and language. As it is known language acquisition in young deaf children is a lengthy process, but cochlear implanted children have better spoken language skills than if they had not received the device. According to the importance of cochlear implant in deaf childchr('39')s language development, this study evaluates the...

Cisplatin is widely used for the chemotherapy of head and neck cancer. However, it has a significant ototoxicity. Nigella sativa been scientifically proven to have numerous benefits included prevent adverse effect drug. This literature review aimed evaluate protective role N. oil against cisplatin-induced Relevant publications were searched from PubMed Google Scholar databases within last 10 ye...

objectives: the aim of present study was evaluation of saccule function in cochlear implant candidates with severe to profound sensory neural hearing loss before and after cochlear implantation methods: in this study 35 cochlear implant (ci) candidates with bilateral severe to profound sensory neural hearing loss before and about 30 days after cochlear implant and 20 normal-hearing cases as a c...

We have examined the effect of restricted unilateral cochlear lesions on the orderly topographic mapping of sound frequency in the auditory cortex of adult guinea pigs. These lesions, although restricted in spatial extent, resulted in a variety of patterns of histological damage to receptor cells and nerve fibres within the cochlea. Nevertheless, all lesions resulted in permanent losses of sens...

Contemporary research efforts have provided new insight into the processes underlying common hearing impairments include aging, genetic defects, and environmental stress such as excessive noise (NIHL) or chemotherapeutic drugs. The primary cause of hearing impairment involves the death of sensory cells (hair cells) and neurons in the cochlea which are irreplaceable in mammmals. Rehabilitative m...

The occurrence of tinnitus can be linked to hearing loss in the majority of cases, but there is nevertheless a large degree of unexplained heterogeneity in the relation between hearing loss and tinnitus. Part of the problem might be that hearing loss is usually quantified in terms of increased hearing thresholds, which only provides limited information about the underlying cochlear damage. More...

This review evaluates the published basic science and clinical reports related to the role of melatonin in reducing the side effects of aminoglycosides and the cancer chemotherapeutic agent cisplatin, in the cochlea and vestibule of the inner ear. A thorough search of the literature was performed using available databases for the purpose of uncovering articles applicable to the current review. ...

Noise exposure causes damage of multiple cochlear cell types producing permanent hearing loss with important social consequences. In mammals, no regeneration of either damaged hair cells or auditory neurons has been observed and no successful treatment is available to achieve a functional recovery. Loads of evidence indicate adipose-derived stem cells (ASCs) as promising tools in diversified re...
